You are running an application on multiple virtual machines within a managed instance group and have autoscaling enabled. The autoscaling policy is configured so that additional instances are added to the group if the CPU utilization of instances goes above 80%. VMs are added until the instance group reaches its maximum limit of five VMs or until CPU utilization of instances lowers to 80%. The initial delay for HTTP health checks against the instances is set to 30 seconds. The virtual machine instances take around three minutes to become available for users. You observe that when the instance group autoscales, it adds more instances then necessary to support the levels of end-user traffic. You want to properly maintain instance group sizes when autoscaling.
What should you do?

• A.Use a TCP health check instead of an HTTP health check.
• B.Decrease the maximum number of instances to 3.
• C.Set the maximum number of instances to 1.
• D.Increase the initial delay of the HTTP health check to 200 seconds.

You significantly changed a complex Deployment Manager template and want to confirm that the dependencies of all defined resources are properly met before committing it to the project. You want the most rapid feedback on your changes. What should you do?

• A.Use granular logging statements within a Deployment Manager template authored in Python.
• B.Monitor activity of the Deployment Manager execution on the Stackdriver Logging page of the GCP Console.
• C.Execute the Deployment Manager template against a separate project with the same configuration, and monitor for failures.
• D.Execute the Deployment Manager template using the ?preview option in the same project, and observe the state of interdependent resources.
